Did you know that there are 583 species of carnivorous plants around the world, which derive nutrition by eating other animals like insects? They are usually found in areas with poor soil quality, like marshes and bogs, that cannot provide these plants with all the nutrition they need. These soils are known to be especially poor in nitrogen. Hence, the plants have evolved the ability to catch and digest insects, which are a good source of protein -- and thus, nitrogen.

You tell him/her what your problem is, s/he examines you with a stethoscope to monitor your heartbeat at various regions of your body and then you get some medicines.

Researchers have always used bacteria, yeast, worms, fruitflies, fish and rodents in laboratories since experimentation on humans is often unfeasible and presents with an ethical conundrum. These model organisms are chosen depending on the nature and complexity of study and the cost and convenience of its maintenance. Zebrafish (Danio rerio) is today a favourite model organism for various biological research studies for well deserved reasons.
